A time series is an ordered sequence of values that are made over a time interval. You can use time series in statistics, communications, and social networks. I this tutorial we are going to create a simple stock time series Node.js library using Redis Strings. This library records events per second, minute, hour, and day.
Redis (REmote DIctionary Server) is an advanced key-value data store. Read and write operations in Redis are very fast because it saves all data in the memory. Redis can also save data on the hard drive. The official Redis documentation can be found at http://redis.io. Redis is an open sources project used by many companies including Instagram and Twitter. In this tutorial, we will install Redis, install Node.js, and try out several data types.
